Inter Milan midfielder Radja Nainggolan admits he's had no feedback from Belgium coach Roberto Martinez since last year.

Nainggolan was controversially omitted from Belgium's World Cup squad last summer.

But he revealed, “I didn't miss a single game played in Russia, it was incredible, an excellent result. I have always supported my teammates and I always will, but I would've liked to have been part of the national team.

“I would have liked an explanation, but no-one ever came to tell me why I was no longer being called up and that bothered me.

“I think it's all very sad, but it's important to me to be a man of my word. I said I wouldn't play for Belgium again and I kept my word."
